ARP Pro Series Rod Bolt Kit BMW E37 740 4.4L M62 96-01

Because factory connecting rods (or aftermarket versions of OEM rods) are used in a variety of applications from rebuilt stock motors to modified powerplants used in circle track, marine and drag racing engines - including those with superchargers and/ or nitrous oxide injection systems - ARP offers replacement rod bolts that are substantially better than the stock OEM and most aftermarket bolts.

For the most severe applications, in conjunction with aftermarket I-beam rods, ARP has developed the "Pro" Series Wave-Loc bolts. These ultra heavy-duty rod bolts are made from a special material designated ARP2000. It has approximately 200% the fatigue life of 8740 chrome moly steel and has a tensile strength of about 220,000 psi, and is capable of more than 12,000 lbs. clamping force.

ARP is the one company you need in your vehicles engine when
building something for high horsepower. The ARP head studs, rod
bolts, and main studs are some of the most popular engine
components upgraded. ARP’s product line contains thousands of part
numbers, and has expanded to include virtually every fastener found
in an engine and driveline. These range from quality high
performance OEM replacement parts to exotic specialty hardware for
Formula 1, IndyCar, NASCAR and NHRA drag racing and marine
applications.
